New owner and looking for previous history

[Munkii]

Hi
I have just bought a yellow beat on the isle of man and was wondering if anyone here recognizes it (there can't be more than one beat on this rock haha)
Just wondering if there was anything hidden as the body/engine seem in good nick (for its age)

looking for history on following cars
K83GTW yellow
JI8EET silver
J509JOU red
L571LHJ silver
does anyone on here have any knowledge of these or used to own them etc

JI8EET is a pretty cool reg number for one..

Unfortunately can shed any light on the cars above

J18EET was on ebay not long ago. Guy was selling beat parts, I thought he was breaking a couple.I enquired after the reg number but the joker asked for £800 for the plate. I impolitely declined due to the tone of his message and the cost.
